There are also provided films made using these air and water barrier articles and building envelopes made using such films.

FIELD

The present disclosure relates to air and water barrier articles and rolls thereof The present disclosure also is related to films and building envelopes made using these air and water barrier articles.

BACKGROUND

Air barrier systems control movement of air, and specifically water vapor, across a surface of a structure, such as a building enclosure. In exterior walls, uncontrolled air flow is the greatest source of moisture and condensation damage. Indoor comfort is affected by air temperature, relative humidity, direction of airflow and surrounding surface temperatures. Indoor air quality is enhanced by air barrier systems by efficiently keeping pollutants out of building interiors. Pollutants include water vapor, suspended particulates, dust, insects, smells, etc. Air barrier systems have significant impact on electricity consumption and gas bills. Air barrier systems in nonresidential buildings are estimated to reduce air leakage by up to 83 percent, reduce heating bills more than 40% and reduce electricity consumption more than 25% according to simulations by the National Institute of Standards and Technology (NIST) compared to typical buildings without air barriers. Water vapor is a key ingredient in corrosion and mold growth. Air barrier systems help prevent water vapor from being transported by air movement between exteriors and interiors of structures, such as buildings.

The use of air barrier systems has been a requirement in Canada for almost 25 years and is becoming important in North America due to net zero energy requirements by 2030, required by the U.S. Army Corp of Engineering, ASHRAE 90, and International Energy Conservation Code—2009. On Dec. 16, 2011, the DC Construction Codes Coordinating Board (CCCB) adopted the 2012 International Energy Conservation Code (IECC).

Previously known waterproofing sheets having both waterproofing property and moisture permeability have been developed. One typical example of such moisture- permeable waterproofing sheets is flash-spun fabrics. U.S. Pat. No. 3,169,899, for example, discloses a flash-spun fabric. U.S. Pat. No. 3,532,589 discloses a method for producing a flash-spun fabric. The fabric thus obtained has an appropriate pore size. It blocks water, but allows water vapor to pass therethrough. A known example of the fabric is commercially available under the trade designation “Tyvek” from E. I. Du Pont de Nemours and Company, Wilmington, Del. USA obtained by thermo-compressing a three-dimensionally-meshed fiber of high-density polyethylene. Such a moisture-permeable waterproofing sheet can prevent external water from infiltrating through the sheet, but can drain gathered moisture as water vapor.

However, the openings such as windows or doors are not flat. It is difficult to form a waterproofing layer only with a waterproofing sheet, and therefore the opening is often finished with a waterproofing tape with a pressure sensitive adhesive layer provided thereon. In this case, since the pressure sensitive adhesive layer is made of rubber or asphalt materials, the moisture permeability of the entire tape decreases, and the same problem as that of a common waterproofing sheet can occur.

Mechanical fasteners or adhesive fasteners, such as pressure sensitive adhesive tapes, can be used to affix the moisture-permeable waterproofing sheet on substrates of exterior walls or to affix overlapped portions of two moisture-permeable waterproofing sheets. As a result, moisture may permeate from gaps of such fasteners, such as nail holes or pressure sensitive adhesive tapes, over a long period of time. It is beneficial for such moisture-permeable waterproofing sheets to pass ASTM D-1970/D-1970M-13 or similar modified tests such as Modified Test 1 of ASTM D-1970/D-1970M-13, Modified Test 2 of ASTM D-1970/D-1970M-13, or Modified Test 3 of ASTM D-1970/D-1970M-14 for nail sealability. It is also beneficial to provide easy application of the air and water barrier article to substrates, such as building components, by not having to remove the release liner before or during application. However, without low release force on the edge of the pressure sensitive adhesive tape, it can be difficult to initiate the removal of the liner. It is beneficial to have an easy peel tab.

SUMMARY

A (meth) acrylic ester polymer having a reactive silicon group may be added to the curable composition of the present invention if necessary. A (meth) acrylic ester monomer composing the main chain of the above-mentioned (meth) acrylic ester polymer is not particularly limited and various monomers may be used. Examples thereof include (meth) acrylic ester monomers such as methyl (meth) acrylate, ethyl (meth) acrylate, n-propyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl (meth) acrylate, isobutyl (meth) acrylate, t-butyl (meth) acrylate, n-pentyl (meth) acrylate, n-hexyl (meth) acrylate, cyclohexyl (meth) acrylate, n-heptyl (meth) acrylate, n-octyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, nonyl (meth) acrylate, decyl (meth) acrylate, dodecyl (meth) acrylate, phenyl (meth) acrylate, tolyl (meth) acrylate, benzyl (meth) acrylate, 2-methoxyethyl (meth) acrylate, 3- methoxybutyl (meth) acrylate, 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, stearyl (meth) acrylate, glycidyl (meth) acrylate, 2-aminoethyl (meth) acrylate, gamma- (methacryloyloxypropyl) trimethoxysilane, gamma-(methacryloyloxypropyl) dime thoxymethylsilane, methacryloyloxymethyltrimethoxysilane, methacryloyloxymethyltriethoxysilane, methacryloyloxyme thyldimethoxymethylsilane, methacryloyloxyme thyldiethoxymethylsilane, ethylene oxide adduct of (meth) acrylic acid, trifluoromethylmethyl (meth) acrylate, 2-trifluoromethylethyl (meth) acrylate, 2- perfluoroethylethyl (meth) acrylate, 2-perfluoroethyl-2- perfluorobutylethyl (meth) acrylate, perfluoroethyl (meth) acrylate, trifluoromethyl (meth) acrylate, bis (trifluoromethyl) methyl (meth) acrylate, 2- trifluoromethyl-2-perfluoroethylethyl (meth) acrylate, 2- perfluorohexylethyl (meth) acrylate, 2-perfluorodecylethyl (meth) acrylate, and 2-perfluorohexadecylethyl (meth) acrylate.

With respect to the (meth) acrylic ester polymer, the following vinyl monomers can be copolymerized together with a (meth) acrylic ester monomer. Examples of the vinyl monomer are styrene monomers such as styrene, vinyltoluene, alpha-methylstyrene, chlorostyrene, styrenesulfonic acid and its salts; fluorine-containing vinyl monomers such as perfluoroethylene, perfluoropropylene, and vinylidene fluoride; silicon-containing vinyl monomers such as vinyltrimethoxysilane and vinyltriethoxysilane; maleic anhydride, maleic acid, and monoalkyl and dialkyl esters of maleic acid; fumaric acid, and monoalkyl and dialkyl esters of fumaric acid; maleimide monomers such as maleimide, methylmaleimide, ethylmaleimide, propylmaleimide, butylmaleimide, hexylmaleimide, octylmaleimide, dodecylmaleimide, stearylmaleimide, phenylmaleimide, and cyclohexylmaleimide; nitrile group-containing vinyl monomers such as acrylonitrile and methacrylonitrile; amido group- containing vinyl monomers such as acrylamide and methacrylamide; vinyl esters such as vinyl acetate, vinyl propionate, vinyl pivalate, vinyl benzoate, and vinyl cinnamate; alkenes such as ethylene and propylene; conjugated dienes such as butadiene and isoprene; and vinyl chloride, vinylidene chloride, allyl chloride, and allyl alcohol. They may be used alone or a plurality of them may be copolymerized. Of them, in terms of properties such as the physical properties of a produced material, polymers comprising a styrene monomer and/or a (meth) acrylic acid monomer are desirable. (Meth) acrylic ester polymers comprising acrylic ester monomers and/or a methacrylic ester monomer are more desirable and acrylic ester polymers comprising acrylic ester monomers are further desirable. In the present disclosure, these desirable monomers may be copolymerized with other monomers and also block-copolymerized with them. In that case, these desirable monomers are desirably contained at a ratio of 40% by weight or higher. In the above descriptions, (meth) acrylic acid means acrylic acid and/or methacrylic acid.

A synthesis method of the (meth) acrylic ester polymer is not particularly limited and a conventionally known method may be employed. A polymer obtained by a common free radical polymerization method using an azo compound, a peroxide or the like as a polymerization initiator has a problem that the molecular weight distribution value is generally as high as 2 or higher and the viscosity is thus high. Accordingly, a living radical polymerization method is desirably employed in order to obtain a (meth) acrylic ester polymer having narrow molecular weight distribution and low viscosity and having a crosslinkable functional group at a molecular chain end at a high ratio. Of the “living radical polymerization methods”, an “atom transfer radical polymerization method” for polymerizing a (meth) acrylic ester monomer using an organic halide, a halogenated sulfonyl compound or the like as an initiator and a transition metal complex as a catalyst has, in addition to the characteristics of the above-mentioned “living radical polymerization methods”, a wide range of the options of the initiator and the catalyst because a halogen, etc. which is relatively advantageous for the functional group conversion reaction is located at a molecular chain end. The atom transfer radical polymerization method is therefore further desirable as a production method of the (meth) acrylic ester polymer having a specified functional group. Examples of the atom transfer radical polymerization method are, for example, the method disclosed in Krzysztof Matyjaszewski et al., J. Am. Chem. Soc, vol. 117, p. 5614 (1995).

Examples of a production method of the (meth) acrylic ester polymer having a reactive silicon group are production methods employing free radical polymerization methods using chain transfer agents and disclosed in Japanese Kokoku Publication H3-14068, Japanese Kokoku Publication H4-55444, and Japanese Kokai Publication H6-211922. Also, a production method employing an atom transfer radical polymerization method is disclosed in Japanese Kokai Publication H9-272714 and the like; and the method is not limited to these exemplified methods. The above-mentioned (meth) acrylic ester polymers having a reactive silicon group may be used alone or two or more kinds of them may be used in combination. A method for producing an organic polymer involving blending a polyoxyalkylene polymer having a reactive silicon group with a (meth) acrylic ester polymer having a reactive silicon group is not particularly limited, and examples thereof include those disclosed in Japanese Kokai Publication S59-122541, S63-11264, H6-172631, and H11-116763. Further, a production method of the polyoxyalkylene polymer obtained by blending the (meth) acrylic ester polymer having a reactive silicon group may also include a method of polymerizing a (meth) acrylic ester monomer in the presence of a polyoxyalkylene polymer having a reactive silicon group. The methods are practically disclosed in Japanese Kokai Publication 559-78223, Japanese Kokai Publication S59-168014, Japanese Kokai Publication S60-228516, and Japanese Kokai Publication 560-228517, and are not particularly limited to them.

Pressure Sensitive Adhesive

In some embodiments, the air and water barrier article s are self-adhering, comprising an adhesive material, preferably a pressure sensitive adhesive material, more preferably a solventless or hot melt pressure sensitive adhesive at least partially coated on an outer major surface of the article. A removable release sheet or liner may advantageously overlay and contact the adhesive in order to prevent the adhesive from adhering to the back side (i.e., non-adhesive coated) major surface of the air and water barrier article in roll form, thereby preventing “blocking” of the rolled air and water barrier article. The release liner is removed prior to applying the air and water barrier article to an architectural structure. Alternatively, the back side major surface of the air and water barrier article may include an overlaid or overcoated low surface energy release layer or low adhesion backsize (LAB); such embodiments are preferably used in linerless articles.

Any pressure sensitive adhesive used to adhere air and water barrier articles to architectural structures (e.g., buildings) may be used. These include both vapor permeable and vapor impermeable pressure sensitive adhesives. An example of the latter is a rubber modified asphalt (bitumen) pressure sensitive adhesive or a synthetic rubber pressure sensitive adhesive. Such pressure sensitive adhesives are well known in the art.

In some embodiments, the adhesive is selected to be a solventless or hot melt adhesive. In some embodiments, solvent based adhesives, water based adhesives may be used. Exemplary types of adhesives include, for example, radiation-cured, e.g., ultraviolet (UV) radiation or electron-beam cured (co)polymers resulting from polymerizable monomers or oligomers) may be used. The applied adhesive is preferably tacky (i.e. sticky) and pressure sensitive.

Suitable hot melt adhesives may contain such ingredients as (co)polymers such as butyl rubber, styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), styrene butadiene (SB), styrene-ethylene-butadiene-styrene (SEBS) and ethylene/vinylacetate (EVA); the following passage describes additives commonly used in hot melt adhesives. They are not typically used as adhesives by themselves. Resins such as those of the hydrocarbon and rosin types hydrocarbons and rosins are employed as tackifiers in hot melt adhesives, natural and petroleum waxes, oil, and bitumen are used as additives, oils, bitumen and others.

Solvent-based adhesives may contain ingredients such as those listed above, dissolved or dispersed in a solvent vehicle. Water based adhesives would normally be based on emulsions of (co)polymeric materials. Suitable (co)polymeric materials include vinyl acetate and (meth)acrylic homopolymers and copolymers the phrase “(meth)acrylic homopolymers and copolymers” is typically used to mean homopolymers and copolymers of one or more (meth)acrylic esters (and acids) only , ethylene/vinyl acetate as well as styrene/acrylic, vinyl chloride/acrylic, vinyl versatate and others. Water based adhesives may have the disadvantage that they generally require the additional use of drying ovens or heat lamps to evaporate the water.

If a vapor permeable pressure sensitive adhesive is used, the air and water barrier article may be completely coated on one side. If a vapor impermeable pressure sensitive adhesive is used, then the air and water barrier article may be only partially coated with adhesive, typically in the range of about 10% to 90%, more typically about 30% to 80%, most typically 40% to 70%, of the surface area of the sheet. In other words, at least 10% to 90%, preferably 30% to 80%, most preferably 40% to 70%, of the surface area of the air and water barrier article should be adhesive-free in order to maintain sufficient vapor permeability of the article.

The adhesive may suitably be applied at a thickness of 0.001 inches to 0.1 inch (about 0.0254-2.54 mm), but is preferably applied at a thickness of 0.003 inches to 0.025 inches (about 0.0762-0.635 mm) and most preferably at a thickness of 0.005 inches to 0.02 inches (about 0.127-0.508 mm).

As noted above, the adhesive may be protected with a strippable release sheet or liner to enable packaging in rolls. Suitable release sheets are paper or (co)polymer film sheets with an overlaying, low surface energy (e.g., silicone) release surface coating.

In some embodiments, release sheets or liners useful in the present disclosure include those made a using a method for producing an at least partially cured layer (optionally a fully cured layer), the method including applying a layer comprising a (meth)acrylate-functional siloxane to a surface of a substrate, and irradiating the layer in a substantially inert atmosphere with a short wavelength polychromatic ultraviolet light source having a peak intensity at a wavelength of from about 160 (+/−5) nanometers (nm) to about 240 (+/−5) nm to at least partially cure the layer. Optionally, the layer is at a curing temperature greater than 25° C.

Thus, in some exemplary embodiments, the material comprising the layer may be heated to a temperature greater than 25° C. during or subsequent to application of the layer to the substrate. Alternatively, the material comprising the layer may be provided at a temperature of greater than 25° C., e.g. by heating or cooling the material comprising the layer before, during, and/or after application of the layer to the substrate. Preferably, the layer is at a temperature of at least 50° C., 60° C. 70° C., 80° C., 90° C., 100° C., 125° C., or even 150° C. Preferably the layer is at a temperature of no more than 250° C., 225° C., 200° C., 190° C., 180° C., 170° C., 160° C., or even 155° C. Release sheets or liners made using such methods are described in detail in WO 2013/032771 A1, the entirety of which is herein incorporated by reference.

Adhesive Patterns

To retain a desired level of water vapor permeance in the air and water barrier articles, the adhesive is preferably applied to the air and water barrier article in a discontinuous manner in order to leave parts, or spots or zones of the major outer surface of the air and water barrier article uncoated with adhesive.

In order to prevent the lateral movement of air between the air and water barrier article and the substrate to which it is bonded, and through lap joints of the air and water barrier article, the adhesive coated areas of the air and water barrier article can be made to intersect to isolate the uncoated areas, thereby eliminating channels through which air can laterally move. This can be achieved by any number of patterns, such as intersecting circles with adhesive free centers, intersecting squares or rectangles of adhesive, intersecting strips in a checkered pattern, etc.

The adhesive may suitably be applied so as to cover 5% to 99% of the area of one side of the membrane, but is preferably applied to cover between 10% and 90% of the area, and most preferably between 50% and 80% of the area, to obtain the optimum balance of adhesion and vapor permeance for the sheet.

Partial coatings of adhesive may be applied in a random fashion or in a specific pattern. Some exemplary partial coatings of adhesive are described, for example, in U.S. Pat. Nos. 3,039,893, 3,426,754, 5,374,477, 5,593,771, 5,895,301, 6,495,229, and 6,901,712. In some embodiments, the presently disclosed air and water barrier article has a moisture vapor transmission rate of 1 perms or more according to ASTM E96 method. In some embodiments, the presently disclosed air and water barrier article has a moisture vapor transmission rate of 5 perms or more according to ASTM E96 method. In some embodiments, the film has a permeability of greater than 10 perms according to ASTM E 96. In some embodiments, thicknesses of the different layers used in the air and water barrier article are varied to achieve desired permeability of the article.

Adhesion Modifying Zone(s)

In some embodiments, the roll also includes an adhesion modifying zone disposed between the second major surface of the article and the first major surface of the liner. In some embodiments, the adhesion modifying zone is used to increase tack or adhesion between the second major surface of the article and the first major surface of the liner when in roll form. Examples of materials or surface treatments useful for increase tack or adhesion between the second major surface of the article and the first major surface of the liner include any chemical or physical surface modifications to any of the second major surface of the article, the first major surface of the liner, or both. For example, a chemical surface modifier can be used. For example, in these cases, the adhesion modifying zone can be a primer, adhesive, adhesion promoter, and the like.

In some embodiments, the adhesion modifying zone is used to reduce tack or adhesion between the second major surface of the article and the first major surface of the liner. Exemplary materials useful to reduce tack or adhesion between the second major surface of the article and the first major surface of the liner include any inherently non tacky materials that can provide a barrier layer between the second major surface of the article and the first major surface of the liner. For example, in these cases the adhesion modifying zone can be inks, release coatings, slip coatings, and the like. Inks useful in the present disclosure include, but are not limited to, those commercially available as liquid, white ink, under the trade designation “DT OPAQUE WHITE” from Sun Chemical Corporation, Carlstadt, N.J. and those commercially available as liquid, red ink, available under the trade designation “SUNSPECTRO SB TRUWEATHER YS RED” from Sun Chemical Corporation, Carlstadt, N.J.

In some embodiments, adhesion modification can be accomplished by selecting a specific liner surface morphology to increase surface area and physical interlocking of the coating.

In some embodiments, more than one adhesion modifying zone is used in order to provide different release forces between the liner and the air and water barrier article of the present disclosure. Referring now to FIGS. 4A and 4B, in some embodiments, a first adhesion modifying zone 40 and a second adhesion modifying zone are disposed between the liner 25 and the air and water barrier article 21. First adhesion modifying zone 40 and second adhesion modifying zone 42 can be positioned in various configurations provided that both of them contact liner 25. As shown in FIG. 4A, first and second adhesion modifying zones (40 and 42, respectively) can be positioned next to and adjacent to one another between the liner 25 and the air and water barrier article 21 to provide two different release forces between the liner 25 and the air and water barrier article 21 when looking at a cross direction cross section of a multilayer article 10 disclosed herein.

As shown in FIG. 4B, in some embodiment, second adhesion modifying zone 42 can be positioned adjacent to a portion of first adhesion modifying zone 40 and on top of a portion of adhesion modifying zone 40. First and second adhesion modifying zones (40 and 42, respectively) of this embodiment are still disposed between the liner 25 and the air and water barrier article 21.

As shown in FIG. 5, when viewing a top plan view of a cross section of the multilayer article 10 disclosed in FIGS. 4A and 4B taken along line A, first adhesion modifying zone 40 extends along one side of the article 10 in the machine direction and second adhesion modifying zone 42 extends the opposite side of the article 10 in the machine direction.

In some embodiments, such as those shown in FIGS. 4A, 4B and 5, a particular ratio of the width in the cross direction of the first adhesion modifying zone 40 to the width in the cross direction of the second adhesion modifying zone 42 is useful in obtaining a desired ease of separation of the liner from the air and water barrier article. For example, in some embodiments, useful ratios of the width in the cross direction of the first adhesion modifying zone 40 to the width in the cross direction of the second adhesion modifying zone 42 ranges from 3:1 to 10:1. In some embodiments, useful ratios of the width in the cross direction of the first adhesion modifying zone 40 to the width in the cross direction of the second adhesion modifying zone 42 include 56:4, 26:4, 58:2, and 28:2. For example, the first adhesion modifying zone can have a width of about 28 inches in the cross direction while the corresponding second adhesion modifying zone can have a width of 2 inches in the cross direction. In some embodiments, such as those shown in FIGS. 4A, 4B and 5, it is useful to control the amount of release force between the first adhesion modifying zone 40 and the liner 25 versus the amount of release force between the second adhesion modifying zone 42 and the liner. For example, in some embodiments, a useful a ratio of a release force of the first adhesion modifying zone 40 from the liner 25 to a release force of the second adhesion modifying zone 42 from the liner 25 is at least 1:13

Test Methods Nail Sealability

Nail sealability of air and water barrier article s was evaluated generally as described in ASTM D-1970/D-1970M-13: “Standard Specification for Self-Adhering Polymer Modified Bituminous Sheet Materials Used as Steep Roofing Underlayment for Ice Dam Protection”, Paragraph 7.9: “Self Sealability. Head of Water Test” with some modifications. All materials were conditioned at (23° C. (73° F.)) for at least 24 hours prior to use. Two different modified tests were employed. Samples were considered to have passed the test if a rating of “A” or “B” was achieved.

Modified Test 1 of ASTM D-1970/D-1970M-13

A plywood substrate having a thickness of 1.25 cm (0.5 inches) was employed; four nails were driven through the air and water barrier article into the plywood substrate until 6.35 millimeters (0.25 inches) remained above the exposed surface of the air and water barrier article; and a red dye was added to the water. After exposure the surface of plywood substrate in contact with the air and water barrier article (referred to herein as the “topside”), and the surface of the plywood substrate opposite the topside (referred to herein as the “bottomside”) were inspected visually by unaided eye for signs of water leakage as determined by the presence of red-stained areas around each of the four nails. Such stained areas would be indicative of failure of the air and water barrier article to form a seal around the nails. Samples were rated “A” if 3 or 4 of the nail areas on the plywood substrate were free of dye staining; “B” if 2 of the nail areas on the plywood substrate were free of dye staining; and “C” if 1 or 0 of the nail areas on the plywood substrate were free of dye staining.

Modified Test 2 of ASTM D-1970/D-1970M-13

Modified Test 2 was conducted in the same manner as Modified Test 1 with the following change. The four nails were driven through the air barrier article into the plywood substrate until the nail head contacted the top surface of the air and water barrier article, then the nail was backed out until 6.35 millimeters (0.25 inches) remained above the exposed surface of the air and water barrier article.

Modified Test 3 of ASTM D-1970/D-1970M-14

Modified Test 3 was conducted in the same manner as Modified Test 2 with the following change. The nails were not backed out, but left in contact with the top surface of the air and water barrier article.

Moisture Vapor Transmission

Moisture vapor transmission of air and water barrier article s was evaluated generally as described in ASTM E96/E96M-13: “Standard Test Methods for Water Vapor Transmission of Materials” using Paragraph 11: Dessicant Method at (23° C. (73° F.)) and 50% relative humidity, with the following modifications. One specimen was evaluated, with the pressure sensitive adhesive facing into the Petri dish; six data points were obtained and used to calculate a permeance value. The six individual values were used to determine an average permeance value which was reported in units of Perms.

180° Angle Peel Adhesion Test 1 (Easy Side Release=Adhesive Strength)

The 180 degree peel adhesion strength between the release liner and pattern coated pressure sensitive adhesive, also referred to herein as the “easy side release”, was measured on a laminate of release liner/pattern coated pressure sensitive adhesive/porous layer. Adhesive strength was measured after aging for seven days at 23° C. and 50% relative humidity. A 2.54 cm wide by approximately 20 cm (1 in. by 8 in.) long sample of the laminate was cut using a specimen razor cutter. The exposed release liner surface was attached lengthwise to the previously cleaned aluminum platen surface of a peel adhesion tester (Model SP3M90, IMASS Incorporated, Accord, Mass.). The laminate was then rolled down one time in one direction with a 2 kg (4.4 lb.) rubber roller at a rate of 230 cm/minute (90 in/min.). The pressure sensitive adhesive/porous layer was carefully lifted away from the release liner adhered to the platen surface, doubled-back at an angle of 180 degrees, and secured to the clamp of the peel adhesion tester. The 180 degree angle peel adhesion strength was then measured as the pressure sensitive adhesive/porous layer was peeled from the release liner at a rate of 230 cm/min (90 in/min). A minimum of two test specimens were evaluated with results obtained in ounces (oz)/inch which were used to calculate the average release strength. Release testing was conducted under Condition A described in 180° Angle Peel Adhesion Test 2 (Tight Side Release=Liner Release) below.

180° Angle Peel Adhesion Test 2 (Tight Side Release =Liner Release)

The 180 degree peel adhesion strength between the release liner and polymeric material, also referred to herein as the “tight side release”, was measured on a laminate of release liner/polymeric material/porous layer. The same procedure as described for “180° Angle Peel Adhesion Test 1 (Easy Side Release=Adhesive Strength)” was used with the following modification. The polymeric material/porous layer was carefully lifted away from the release liner adhered to the platen surface, doubled-back at an angle of 180 degrees, and secured to the clamp of the peel adhesion tester. The 180 degree peel adhesion strength between the release liner and polymeric material was measured after all aging conditions (A, B, and C) given below.

-   -   A) After 7 days at 23° C. (73° F.) and 50% relative humidity         (RH);     -   B) After 7 days at 70° C. (158° F.) followed by equilibration         for 4 hours at 23° C./50%RH;     -   C) After 7 days at 32° C. (90° F.) followed by equilibration for         4 hours at 23° C./50%RH.

EXAMPLES Example 1

An air and water barrier article having a porous layer partially impregnated and covered on one side with a polymeric material and having a discontinuous pressure sensitive adhesive layer disposed on the side of the porous layer opposite the side that was coated with the polymeric material was prepared as follows. The polymeric material composition was provided by charging the following materials into a mixing vessel that was then place in a dual asymmetric centrifuge mixer: 39.8 parts by weight (hereinafter abbreviated as “pbw”) of a silyl-terminated polyether, KANEKA MS POLYMER 5203H, 1.25 pbw of hydrophobic fumed silica, AEROSIL R202, 26.7 pbw of calcium carbonate OMYACARB 5-FL, and 4.4 pbw of titanium oxide, TIONA 696. After mixing at 2500 rpm for four minutes 0.87 pbw of an aminosilane, DYNASYLAN DAMO-T, 0.87 pbw of a vinyl trimethoxysilane, DYNASYLAN VTMO, and 0.19 pbw of a tin catalyst, NEOSTANN U-220H, were added and mixed at 2500 rpm for two minutes. This final mixture was used to coat a silicone treated, polyethylene-coated Kraft paper using a notch bar coater having a gap setting that was 0.30 millimeters (0.012 inches) greater than the thickness of the release paper. The coated release paper then laminated to a porous layer, REEMAY 2024 polyester, at room temperature (23° C. (73° F.)) using a hand roller and negligible pressure. This laminate construction was cured at 93° C. (200° F.) for 8 hours. The release paper then was removed to give a partially impregnated air and water barrier article having a continuous layer of polymeric material on one side of a porous layer, and having an approximate total thickness of 0.33 millimeters (0.0128 inches).

A pressure sensitive adhesive composition was prepared by mixing 99 parts pbw isooctyl acrylate (IOA), 1 pbw acrylic acid (AA) and 0.04 pbw of a photoinitiator, IRGACURE 651. This mixture was partially polymerized under a nitrogen atmosphere by exposure to low intensity ultraviolet radiation to provide a coatable syrup having a viscosity of about 4000 cps. An additional 0.26 pbw of IRGACURE 651, 0.13 pbw of a Triazine, and 6 pbw of a tackifier, FORAL 85LB, were added to the syrup and mixed until all of the components had completely dissolved to give a pressure sensitive adhesive precursor composition. The precursor composition was coated at a line speed of 2.74 meters/minute (9 feet/minute) onto a silicone treated, polyethylene coated Kraft paper liner.

The pressure sensitive adhesive precursor composition was provided to dispensing outlets on both a first distribution manifold and a second distribution manifold. The dispensing outlets on the first manifold, spaced 12.5 millimeters (0.5 inches) apart, were reciprocated at a rate of 1.67 Hz and a peak-to-peak amplitude of 12.5 millimeters (0.5 inches) in the width-wise direction of the liner as it moved in its' length-wise direction, while the dispensing outlets on the second manifold, spaced 12.5 millimeters (0.5 inches) apart, were kept stationary.

The coating weight was 0.013 grams/square centimeter (32 grains per a 4 inch by 6 inch area). The coated liner was then exposed to ultraviolet radiation having a spectral output from 300-400 nm with a maximum at 351 nm in a nitrogen-rich environment. An intensity of about 9.0 milliWatts/square centimeter was used during the exposure time, resulting in a total energy (dose) of 1800 milliJoules/square centimeter.

The result was a pattern of parallel sinusoids of the pressure sensitive adhesive composition aligned in the longitudinal direction of the paper liner and positioned between the straight line stripes of the pressure sensitive adhesive composition. The sinusoidal patterns contacted the straight line patterns. The adhesive covered approximately 56% of the area of the liner surface, with approximately two thirds of that being attributable to the sinusoidal patterned adhesive and approximately one third of that being attributable to the straight line patterned adhesive.

For nail sealability evaluation the paper liner containing the pattern-coated pressure sensitive adhesive was transfer laminated using hand pressure to a 12.7 millimeter (0.5 inch) thick piece of plywood substrate. Next, the air and water barrier article was laminated by hand to the plywood substrate such that the porous layer covered the patterned coated pressure sensitive adhesive layer. This article was then evaluated for nail sealability test method 1.

Measurement of water vapor transmission was conducted on a sample prepared by directly laminating the exposed pressure sensitive adhesive surface of the pattern-coated pressure sensitive adhesive paper liner onto the non-coated surface of the air and water barrier precursor material. This was rolled down by hand using a rubber roller to ensure transfer of the adhesive onto the air and water barrier precursor article to give an air and water barrier article having a pattern coated pressure sensitive adhesive on one side and a polymeric material coated on the opposite side. The results are shown in Table 1.

The pressure sensitive adhesive layer was applied to one side. The resulting encapsulated air and water barrier article was evaluated by the modified nail sealability test methods.

Example 10

Example 6 was repeated with the following modifications. The porous layer used was impregnated with the silyl-terminated polyether as follows. A sample of the porous layer, measuring approximately 30.5 centimeters long and 15.2 centimeters wide (12 inches by 6 inches), was immersed in a bath of the silyl-terminated polyether, pulled out by hand, the majority of excess polyether wiped off with a wooden scraper, then hung vertically for 24 hours at room temperature. It was then placed in an oven at 93° C. (200° F.) for eight hours to provide a nontacky, impregnated, encapsulated air and water barrier article. The pressure sensitive adhesive layer was applied to one side. Nail sealability was determined using test method 2.
